“…Nowadays, different theoretical approaches, mainly based on the use of mean-field selfconsistent calculations, have been used for the in silico prediction of the performance of different model conditioning formulations [11,[71][72][73][74]. The results obtained following the abovementioned theoretical approaches are generally in good accordance with the experimental findings [7,45,46].…”

“…These surfactants are considered to be the most efficient in the cleaning of sebum fats and dirt in general. However, an excessive deposition of this surfactant onto the surface of the hair fibers during the washing process may increase the number of negative charges, which would be detrimental for the conditioning process as result of the increase in the friction [7,[41][42][43][44][45][46]. • Cationic surfactants.…”

“…They have good foaming, detergent and wetting properties and are very mild, presenting excellent dermatological properties; therefore, they are used to reduce the aggressiveness of anionic surfactants. The most common are N-alkyl betaines, derived from trimethylglycine (betaine) [45,46,48].…”

Most of the currently used products for repairing and conditioning hair rely on the deposition of complex formulations, based on mixtures involving macromolecules and surfactants, onto the surface of hair fibers. This leads to the partial covering of the damaged areas appearing in the outermost region of capillary fibers, which enables the decrease of the friction between fibers, improving their manageability and hydration. The optimization of shampoo and conditioner formulations necessitates a careful examination of the different physicochemical parameters related to the conditioning mechanism, e.g., the thickness of the deposits, its water content, topography or frictional properties. This review discusses different physicochemical aspects which impact the understanding of the most fundamental bases of the conditioning process.

“…The preparation of the aqueous mixtures used in this work was performed following a procedure that was adapted from our previous studies [29,30,45,49,50]. This procedure can be briefly summarized in the following steps: (i) the required amount of an aqueous commercial solution of PDADMAC (concentration 200 g/L) for obtaining final mixtures with a polymer concentration of 5 g/L was weighted and poured into a flask; (ii) surfactant was added and this was diluted accordingly to reach final concentration.…”

“…Hence, the study of the behavior of these systems in solutions and upon their adsorption at interfaces-both fluid/fluid and fluid/solid-may help in understanding the main physico-chemical bases governing the processes involving the performance of shampoos [25,26]. In particular, the performance of hair conditioner formulations is related to the layer of polyelectrolyte-surfactant complexes adsorbed on the hair fibers after drying the hair [27][28][29][30][31][32]. It should be noted that together with the cosmetic industry, polyelectrolyte-surfactant mixtures are widespread in many other industries, ranging from detergency to tertiary oil recovery, and from dietary products and pharmaceutics to wood pulping [27,[33][34][35], with the understanding of the combined effect of evaporation and adsorption of surface active compounds to the involved interfaces being critical for their optimization [36,37].…”

The wetting and evaporation behavior of droplets of aqueous solutions of mixtures of poly(diallyldimethylammonium chloride) solution, PDADMAC, with two different anionic surfactants, sodium laureth sulfate, SLES, and sodium N-lauroyl N-methyl taurate, SLMT, were studied in terms of the changes of the contact angle θ and contact length L of sessile droplets of the mixtures on silicon wafers at a temperature of 25 °C and different relative humidities in the range of 30–90%. The advancing contact angle θa was found to depend on the surfactant concentration, independent of the relative humidity, with the mixtures containing SLES presenting improved wetting behaviors. Furthermore, a constant droplet contact angle was not observed during evaporation due to pinning of the droplet at the coffee-ring that was formed. The kinetics for the first evaporation stage of the mixture were independent of the relative humidity, with the evaporation behavior being well described in terms of the universal law for evaporation.

Precipitation or coprecipitation of polyelectrolytes has been largely investigated. However, the precipitation of polyelectrolytes via addition of charged and non‐charged surfactants has not been systematically studied and reported. Consequently, the aim of this work is to investigate the effect of different surfactants (anionic, cationic, non‐charged and zwitterionic) on the precipitation of cationic and anionic polymethylmethacrylate polymers (Eudragit). The surfactants effect has been investigated as a function of their concentration. Special attention has been dedicated to the CMC range and to the colloidal characterization of the formed dispersions. Moreover, the effect of salt (NaCl) and pH was also addressed. It is pointed out that non‐ionic and zwitterionic surfactants do not interact with charged Eudragit E100 and L100. For oppositely charged Eudragit E100/SDS and Eudragit L100/CTAB, precipitation occurs, and the obtained dispersions have been characterized in terms of particle size distribution and zeta potential. It was established that the binding of SDS molecules to Eudragit E100 polymer chains is made through the negative charges of the surfactant heads under the CMC value whereas binding of CTAB to Eudragit L100 chains is made at a CTAB concentration 5 times above its CMC. For Eudragit E100/SDS system, a more acidic medium induces aggregation. A same result was observed for the Eudragit L100/CTAB at a more basic pH. Moreover, it was observed that increasing salt concentration (higher than 100 mM) led to aggregation as generally observed for polycations/anionic surfactant systems.
